The American dramatist Katori Hall has created a work of rare accomplishment in Our Lady of Kibeho, a play that combines a beautifully established picture of a particular world – a church school in rural Rwanda, in the early 1980s – with profound themes such as faith and belief.

Reviewing Ian McKellen's show is, in one sense, like appraising the Taj Mahal or Mount Everest: he too is an awe-inspiring phenomenon.

Playwright Peter Nichols died aged 92 last month, just before the opening of this starry West End revival of his most celebrated masterpiece. A Day in the Death of Joe Egg (1967) is based on his own family experience of bringing up his disabled daughter in the 1960s, and it has the reputation of being one of the most ground-breaking plays of its generation.

Time has been kind to Athol Fugard's "Master Harold"...and the Boys. It's a stealth bomb of a play that I saw in its world premiere production in New Haven, Connecticut, in 1982 and that has been a regular part of my playgoing life ever since. Yes, the apartheid-era South Africa that Fugard dissects with terrifying force has been dismantled, and we live in (supposedly) more enlightened times.

What a joy Laura Wade's latest play is. Transferring from its successful run at the Minerva Theatre at Chichester last year, The Watsons is developed from Jane Austen's unfinished novel (started in 1804 and abandoned the following year).

There’s a fine balance between the cosmic and the closely crafted in director Paul Miller’s Macbeth, his first production in the expansive space that is Chichester’s main stage.

At the age of 81, Caryl Churchill, Britain's greatest living playwright, is still going strong. Her latest is a typically imaginative quartet of short plays. Each of them is vividly distinct, being linguistically agile, theatrically pleasurable and emotionally dark, yet all are also united by the common theme of folk tales and strongly archetypal stories.

An all-girl rock group from the 1980s meet again, 30 years after an acrimonious break-up brought their shared stage career to an end … and the sparks fly as old resentments resurface and the bitterness of life’s blows emerges. Will their one-time all-girl solidarity overcome their pain and regrets? Will the show end with them back together, belting out their iconic anthem?

Are first ladies second-class citizens? Do they always have to stand behind their husbands? What are they really like as people? Questions such as these have inspired Irish playwright Nancy Harris to explore the relationship between two fictional first ladies, each of which bears an uncanny resemblance to a real-life figure. One is clearly based on Melania Trump, the other on Brigitte Trogneux, better known as Mrs Macron.

Earthiness, lyricism, fatalism, the undeniable force of passion, of ecstatic attraction, known as "duende": these are the familiar ingredients of Lorca's plays set in rural Spain. Blood Wedding, written in 1932, was the first, followed by Yerma two years later and The House of Bernarda Alba in 1936, the year of Lorca's murder by Nationalists. As a gay, left-wing artist - he was a poet and musician as well as a playwright - he was an obvious target.
